Tubegazing: 'King'

King (History Channel, April 6, 8 p.m., E.T.): On the fortieth anniversary of the civil rights leader's assassination, former NBC anchorman Tom Brokaw narrates a comprehensive look at the life and impact of Martin Luther King, Jr. As a young minister, he was chosen by black leaders to galvanize that community during the tumult that followed Rosa Parks's act of civil disobedience. He was selected because he was a "colleged" man, but it was his soulful integration of heady subjects such as existentialism with a vibrant moral and political vision that endeared him to his followers and allowed him to change history.
